ADJUSTABLE HEADREST FOR BARBERS CHAIRS.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed January 15,1920. Serial No. 351,543.

To all whom t may concern Be it known that I, VILLIAM T. Swrrznn, a citizen of the United States of America, and resident of Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful .mprovements in Adjustable Headrests for Barbers Chairs, of which the following is a specification. l

This invention relates to barbers chairs and particularly to adjustable head rests therefor, and still more particularly to novel means whereby the head rest and its supporting bar may be swung clear of the top of the chair, so that when the barber is operating, the head rest and bar will not ob struct free movement of his arms during the process of manipulation.

A still further object of this'invention is to provide novel means whereby the supporting bars of the head rest may be caused to move in a guide in operative relation to the back of the chair, the said bar being capable of swinging outwardly and down-` wardly so that the head rest and bar are carried clear of the top of the chair and guid ing member; novel means being also provided for suspending the parts in the last mentioned positions.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote correspond ing parts in the several views and in whichi Figure 1 illustrates an edge view or :fragment of the back of the chair showing the guiding member and head rest applied thereto.

Fig. 2 illustrates a vertical sectional view of the guiding member showing the bar and its supporting means in place.

Fig. 3 illustrates an edge view of the sup` porting bar and parts connected therewith.

Fig. l illustrates a front view thereof.

Fig. 5 illustrates an enlarged detailed see-' tional view of a fragment of one of the bars and a link connected therewith.

In these drawings l() denotes the back oi a chair and 11 a guiding member, both of which are conventionally shown, and it is the purpose of the inventor not to be limited with respect to the detailed construction of these members.

rllhe guiding member 11, as is usual in these devices, has a channel or clearance 12, in which the bar of the head rest isslidalole and with relation to which it is secured in different positions of adjustment.

The head rest 13 is connected to the toothed bars 14: and 15 which differ from the head rest bars usually used, in that in this form -of the invention, the bars are spaced apart and one slides in the guide on` each side of a stud 16 which is anchored at such distance from the top of the guide as to arrest the yoke 17 when the upper ends 18 of the said yoke 17 are at the upper end of the channel of the guide, so that by this means, the upward movement of the yoke is limited, and the relative positions of the parts are such that links 19 connected to the ends of the yoke and the ends of the bars respectively,may lie approximately horizontally or across the end of the guide at the top, and the length of the links is preferably equal to the thickness or width of the guiding member from the channel to the outer or rear side thereof, so that the bars 14 and 15 may hang vertically with the head rest well below the top of the chair.

I have not in this illustration shown the latch or detent for holding the bars of the head rest at different positions of adjust ment, that being an expedient well known in the art and any one of the known and successful devices may be employed in this connection.

It is believed that the construction and operation of the device will be understood from the drawing and from the foregoing description and the relation. of parts should be substantially as shown and described, as it is by having the proportions so established that the yoke and link are maintained in positions to support the bars without projeetin g unduly vertically or laterally.

1. ln a barbers chair, a head rest, a guiding member, bars connected to the head rest and movable in the guiding member, said bars being spaced apart, said guiding member having a slot therein for the passage of the bars, links pivotally connected to the `ends of the bars and in length equaling eide thereof7 a 'stud anchored transversely 0i the guide-way, and a yoke connected to the links, the length of the yoke being approximately equal to the distance between the stud and the top of the guide-way.

2. In a barbers chair, a guide-way having` clearance space therein, a stud extending through the clearance space, a head rest, a bar Vfor the head rest slidable in the elear- 0 ance space, a link connected to the bar, the

length o1 the link heilig apploxilnately equal to the thickness of the gui le\\ay lwtween the clearance space and the lm k thereof, and a lneinber connected to the Said link adapted to he engaged with the Html for limiting the movement of the link, the length of the said inenlhel' heine` approximately equal to the distance between the stud and the top of the guide-wav.
